Is there any reason the entire left panel couldn’t be tab control my idea is let’s use actions as a example one click it opens without the tabs showing at the top, when you edit the action a blue dot appears in the left navigation area when saving this is back to normal this would be for everything git databases pages everything if possible. Then have some save and close options on actions pages etc etc save and close, save, close without saving
Also for easy access to the open tabs a new active tabs area where you can also choose to split section the open tabs
